Abstract
Ultrasonic measurement of bolt axial stress was briefly introduced including its rationale and testing method, and the formula for bolt elongation and axial stress was derived. The choice of probe, the requirement for the surface condition of the bolt tested, temperature compensation and the condition applicable for measurement were also detailed. It was shown by practical application that the method was easy for operation and high in accuracy.
